Automobile exhaust gases are conventionally purified with a catalyst supported on a ceramic body able to withstand high temperatures. The preferred catalyst support structure is a honeycomb configuration which includes a multiplicity of unobstructed parallel channels sized to permit gas flow and bounded by thin ceramic walls. The walls of these channels provide the surface for precious-metal catalysts that convert noxious emissions into carbon dioxide, nitrogen and water vapor. This catalyst support is often called 'ceramic catalyst support' or 'ceramic honeycomb' or 'Ceramic monolith' or 'catalytic converter substrates' or 'cellular monolith substrates' or 'cellular ceramic catalyst supports'.
We are one of china’s main ceramic catalyst support supplier, which can be used in all kind of cars, buses, trucks, motorcycles, etc. and enable highly efficient emissions control systems by offering:
- High surface area
- Excellent thermal-mechanical durability
- Low pressure drop
- Rapid light-off
- System cost efficiency, especially compare to metal converters.
